Stirring device

The stirring device comprises a rotating shaft and blades, the multiple blades are arranged at intervals in the axial direction, and each blade is fixedly installed on a connecting arm arranged on the rotating shaft; the connecting arm is positioned in a plane vertical to the rotating shaft and is divided into a first arm rod and a second arm rod from inside to outside; the first arm rod is arranged in the radial direction, the second arm rod is bent towards one side relative to the first arm rod, and the blades are installed on the second arm rod in parallel. According to the stirring device disclosed by the utility model, the outer section of the connecting part is bent, so that one surface of each blade faces the rotating shaft to a certain extent, and the blades can push materials to radially flow inwards during stirring and can still push the materials to rotate and flow, so that the flowability of the materials is improved, and the stirring effect is enhanced; the time consumed for uniformly stirring th
